Should PV inverters be made available for utility projects?

These must be made available for utility projects also with proper further advancements. The PV inverters are expected to increase at a 4.64 rate by 2021 and 2022 to meet a target of about 100 GW. The markets are showing many favourable conditions by announcing expansion plans.

Why do PV inverters need MLI topologies?

Increase in voltage handling capability. Fault ride-through capability, high/low voltage, high efficiency, high reliability, high power density, less economic costs, and long lifetime are key challenges that the PV inverter must be able to face. More usage of MLI topologies to minimise the harmonic injection, obtaining medium voltage.

Are autonomous inverter-based solutions a viable solution for high-penetration photovoltaic (PV) production?

The widespread deployment of autonomous inverter-based solutions for mitigating voltage and frequency excursions caused by high-penetration photovoltaic (PV) systems has drawn increased attention due to their potential impact on PV production.

What is voltage source inverter (VSI)?

Voltage source inverter (VSI), Fig. 7a, is one of the traditional configurations of inverters that are connected to a power grid. Even though VSIs can introduce currents with low harmonics into the grid, the output voltage of VSI is lesser than the input voltage. The advantages of this inverter are low cost, robustness, and less losses.

Are sic- or GaN-based PV inverters a good choice?

By enabling SiC- or GaN-based PV inverters will greatly reduce the trade-off between efficiency and performance. They replace the silicon-based devices providing pros such as Compact size, which also works at high temperatures reducing the cost, weight to a still greater extent.
